When Bite-Size returns to the HQ searching for a placed to stay during a storm, this time Koki treats him like a pet, which leads her to argue with Chris, and leads him to hurt her feelings. Convinced that Chris expelled her from the team, and also curious about “her little Bite-Size” ‘s ways of surviving in a dangerous place like the North American forest, Koki runs away with him. Meanwhile, Donita Donata decides to make Bat barrettes, after a brown bat gets stuck on her hair.
Koki drove the Tortuga around the North American Forest, searching for someone. Meanwhile, while fixing the Createrra VX and leading with pesky mosquitoes, the Kratt siblings caught the scent of Jimmy's famous brownies, and after Koki grabs something quickly and leaves the Garage, they start questioning themselves about Koki's behavior early that day.
In the Tortuga's shell, where the whole crew reunites to see the sunset before a storm could star, something hide in Jimmy's brownies, and Koki gets happily surprised: it's no one else than Bite-Size, her little bat friend. After a short reunion, and introducing the Wild Kratts' bat friend to Mina , they hear a thunder that freaks the young nymph and the little brown bat out. Once inside the Tortuga, they lock everything before it starts raining.
When questioned about how they met Bite-Size, Koki admits still feeling terribly guilty about the incident in the "Bat in the Brownies" adventure, still not written in the Wild Kratts Diary. As Bite-Size shivers in his bat box, possibly traumatized by the last time, Koki swears to him that she'll never let anything ever happen to him.
Meanwhile, Donita Donata is forced to land her plane because of the rain, and get freaked out when a brown bat gets in. But once she paralyzed it with her pose beam, she have the idea of making bat berretes.
Later in the HQ, after it stops raining, Koki refuses to let Bite-Size go, making Chris scold her and affirm that "someone that doesn't understand the value of freedom shouldn't be even a member of the team." These hurtful words drive Koki to tears, and upsets everyone else.
Bite-Size finds Koki in the Garage and try giving her some comfort. Koki admits she wanted him to live with them, and this makes her ask herself how a creature like him survive in a place where he can lose his lair quickly. Determined to find the answer, she runs away from the Tortuga with Bite-Size after pickings her CPS and the Bat Power Disk Aviva was adjusting.
Chris, feeling bad for saying such terrible things to Koki, is encouraged by Mina to apologize to her. Once they get in, they find out that Koki's gone, only leaving her Creaturepod behind.
While flying through the forest, Koki and her bat friend are attacked by Donita and Dabio, but succeed in escaping. While stopping to eat, Koki sees a picture of the team and starts thinking that running away was not such a good idea. Soon, she and Bite-Size are forced to escape when a barn owl fly on their direction. Bite-Size helps Koki finding him in an old tree trunk, full of bat mothers and pups. After activating her medallion, Koki meets a young bat pup that lose her mother because of that owl. Meanwhile, determined to find Koki, Chris use the Batronicus VX (built under the Butterflier scheme) to search around the forest.

Chris, with a little help from Aviva, finds that Koki has been kidnapped by Donita and flies on the coordinates' direction. Meanwhile, Donita keeps imagining how fabulous her new fashion statement would, until Koki have an idea to free her friends, by using her amplified echolocation.
